Geochemical Signatures of Covered Mineral Deposits in the Northern Midcontinent

We are evaluating the potential of geochemical prospecting techniques that have shown promise in other covered terranes for mineral exploration in the northern midcontinent of the U.S. Novel components will be added to these methods with the objective of method advancement and improving our understanding of processes controlling the transmission of unique geochemical signatures from buried...

Emerging Geoenvironmental Issues Related to Proposed Mining in the Lake Superior Region

We are studying environmental issues related to mining, and potential mining, in the Great Lakes region, continuing the study of characterizing baseline geochemistry of several watersheds in Minnesota and Michigan, examining the potential for aquatic toxicity from metals, and examining the acid-neutralizing and acid-generating potentials of mine waste, and the environmental, and possible human...

Beryllium: Economic Geology, Material Flow, and Global Importance of a Key Critical Mineral

Beryllium (Be) is a critical metal mineral commodity with unique chemical properties, making it indispensable to the computer, telecommunication, aerospace, medical, defense, and nuclear industries. We are studying known deposits of beryllium to determine where undiscovered beryllium resources might be found, analyzing how and where beryllium becomes concentrated in Earth’s crust, gathering a...

Geologic Map of Alaska

In January 2016, the U.S. Geological Survey released the first ever digital geologic map of Alaska. This map reflects more than a century of work and provides a visual context for the abundant mineral and energy resources found throughout the state. The map also is available to use in three different formats: a professional GIS database, a public interactive version via a web browser, and an...
